gas to liquid
Explanation:
The change of state indicated by this analogy is from gas to liquid.
Cylinder to the left is filled with gases
Cylinder to the right is made up of liquid.
- Gases occupy the volumes of containers they are introduced into.
- They are random and possess a high kinetic energy.
- Liquids have definite volume and flow with one another.
- The gases in A are dispersed and in random motion.
- This phase change is called condensation

Answer:
the volume will increase
Explanation:
The kinetic energy of gas molecules depend upon the temperature . If temperature is increased , the molecules will move faster . When temperature is decreased , they move slower .
Hence when more molecules are added to a gas without changing its temperature , the velocity of gas molecules will remain unchanged .
Since pressure is also constant , it is volume which will be increased .
It can be explained from universal gas formula as follows
PV = nRT
P , R and T is constant ,
V ∝ n
Volume is proportional to n which depends upon number of molecules .
So volume will increase if number of molecules increases .
Answer:
[(x-37.5)/x]*100%
62.5% (assuming the original sample weighs 100.0g)
Explanation:
Let's say that the original sample is x
Mass of I-125 which has decayed: x-37.5
Percentage of decayed mass: [(x-37.5)/x]*100%
